Abstract To keep metal temperature at allowable levels in modern gas turbine engines, both internal and external (film) cooling is necessary, which is represented by an overall cooling effectiveness. Previous studies measured overall cooling effectiveness for first-stage vanes in low-speed experiments, where it is appropriate to use ...

Abstract The overall cooling effectiveness, which represents the distribution of dimensionless temperature on gas turbines surface, is an important parameter for conjugate heat transfer analysis of gas turbines. Generally, it is difficult to measure the overall cooling effectiveness in engine condition.

Abstract One of the most effective ways to cool the combustor liner is through effusion cooling. Effusion cooling (also known as full-coverage effusion cooling) involves uniformly spaced holes distributed throughout the combustor liner wall. Effusion cooling configurations are preferred for their high effectiveness, low-pressure penalty,

Abstract Thermal design for the trailing edge of a turbine vane is critically challenging because the thinnest trailing-edge region has a low-thermal capacity, resulting in a much quicker thermal response to the hot gas. Cooling air for this region is usually extracted from the internal cooling passages inside the vane main body and thus

The cooling system is required to ensure gas turbine can work at high temperature, which has exceeded the material limitation. An endwall cooling test rig was built up to conduct the endwall cooling research. A detailed work was done for analyzing characteristics of endwall heat transfer and discussing the multi-parameter influence mechanism of overall
